Kawasaki S1 parts for repair and restoration
Keep S1 parts distinct from other Kawasaki S-series models.
Kawasaki’s Owner Center shows 1973 diagrams for S1-A/B/C and a 1975 S1-C250 entry. Record the model code and year, then match the part application to your S1.
See the Kawasaki S-series parts for related model guidance.
Identify the S1 hardware
Record the model code, year and sales market. On a restored triple, inspect the carburetors, fork dimensions and fuel cap actually installed.
